Definitions

  • This invention concerns a heat welding unit located at a sealing station for sealing the open ends of monodose containers which have already been filled with liquid or viscous solutions by a monodose packaging machine (FR-A- 1 560 594).
  • Packaging machines which package vaccines, eye drops, enemas etc. in monodose containers are well known.
  • the main purpose of such machines is to package monodose containers so as to safeguard the integrity, the seal and the sterility of their contents.
  • Monodose containers provide:
  • Monodose containers are usually made of polyethylene or polypropylene materials.
  • Polypropylene has a higher melting point than polyethylene, for example, while polpropylene is more environment-friendly.
  • the melting point is a problem which concerns the heat welding or sealing station which forms part of known monodose packaging machines and is located downstream from the filling station on this type of machine.
  • the trimming station also requires a system for collecting and removing the offcuts. Offcuts are, however, never removed completely and are spread around the machine thus creating a cleaning and hygiene problem.
  • the trimming operation itself also creates dust which pollutes a working environment which should, on the other hand, be kept sterile.
  • a further problem caused by the need to trim the monodose ends is that the packaging machine requires an extra station dedicated to trimming and this obviously increases total machine operating costs and the size of the overall area occupied by the machine.
  • the sealing gripper has identical comb-shaped jaws with square prongs where the prongs move towards each other when the jaws are closed.
  • This head also has squared prongs each of which is inserted into the matching seats created by each pair of facing recesses in the jaws of the said gripper; the head does not, however, prevent oscillation of the jaws.
  • the pairs of prongs of the joined jaws fit into the corresponding recesses between the prongs of the head.
  • the container thus maintains an aesthetically pleasing appearance without the need to install a trimming and offcuts recovery station.
  • the gripper has comb-shaped jaws as in the first version; these are offset so that the square prongs of the first jaw are inserted into the square recess between the the prongs of the second jaw.
  • Figure 1 shows an example of a stick 1 consisting of three monodose containers 2.
  • Figures 2 and 3 show known means 3 for picking-up, transporting and compressing ready-filled monodose containers 2 at a point 6 below the open ends 8 of the said monodose container; these means 3 isolate the contents of each monodose container from the surrounding environment.
  • the ends 8 are subsequently heat welded by a sealing unit 4 as shown in figure 3.
  • Figures 4 and 5 show a gripper 10 shaped in accordance with the first version of the invention; 15 and 16 are identical, comb-shaped jaws of the gripper 10, 15A and 16A are square prongs whereas 15B and 16B are the corresponding square recesses between the said prongs.
  • the outward facing surfaces of the prongs have lengthways grooves 15C and 16C (in figure 5 only the first of these are visible since the second set are not visible from this perspective) which form ribbing, with the profiles of the said facing surfaces of the said jaws 15 and 16, which is parallel to the direction of travel of the monodose container 2.
  • the said jaws 15 and 16 pivot around a fulcrum 7 (fig. 3) and are moved apart and brought closer together (arrow B in figures 3 and 4) by known means 9 and 9A.
  • the component 9A acts in the direction indicated by W on a pivot pin 7A suitably linked to said means 9 so that these means move in the direction of an arc indicated by Z in figure 3 thus opening and closing the said gripper.
  • the head 17 is also comb-shaped with square prongs 17A and recesses 17B.
  • the position of the gripper-head assembly during gripper closure is such that the square prongs 17A of the said head 17 fit perfectly into the seat recesses created when the gripper is clamped by the the jaws 15 and 16 corresponding to the recesses 15B and 16B; oscillation of the said jaws 15 and 16 is not prevented in any way.
  • the head 17 acts so as to prevent the formation of unsightly irregular edges at the ends 8 and to ensure that the monodose container heads thus created are all identical.
  • a trimming station downstream from the sealing station is thus not required as is usually the case with known machines.
  • the head is fixed to the components 9 and 9A which pivot on the fulcrum 7 of the gripper 10 and the pivot pin 7A.
  • the stages of the process cycle can be summarised as follows: once the monodose containers have been filled using known methods, their ends 8 are preheated; the monodose containers are then conveyed and positioned by the means 3 between the open jaws 15 and 16 of the gripper 10 next to the prongs 15A and 16A.
  • the prongs 17A inserted into the recesses 15B and 16B and the recess 17B meeting the upper faces of the jaws 15 and 16 are all clamped they ensure the formation of a neat edge on the monodose container so that subsequent trimming of the edge is not necessary; these parts also ensure that all monodose container heads are of the same dimensions. There are consequently no problems arising from offcut recovery or dust in sterile environments.
  • the monodose container stick is aesthetically and functionally ready for packing.
  • the profile of the ends 8 is determined on both sides by the guides A which improve the seal and the appearance of the containers; these guides have the same shape as the grooves 15C and 16C of the prongs 15A and 16A.
  • Figures 6 and 7 show a second version of the gripper 20.
  • 25 and 26 are the comb-shaped jaws of the gripper 20.
  • the jaws 25 and 26 have square prongs 25A and 26A and square recesses 25B and 26B; the jaws are offset so that when the gripper 20 is clamped shut, the prongs 25A are inserted into the recess 26B and the prongs 26A are inserted in the recesses 25B.
  • This configuration prevents the formation of irregular sides when the gripper 20 is closed and ensures that the monodose ends meet the dimensional requirements referred to previously.
  • the operation of the head 27 prevents the formation of unsightly, irregular ends which would otherwise require the installation of a trimming and offcut recovery station (as is usually the case with known machinery).
  • the stages of the heat welding cycle are the same as those previously described for the first version of the sealing unit.
